`My invention relates`A to tie l plates for rail'- roa'd rails, and its object is to provide a new and'. irriprovleddevice of this ch'araotr which when used in the ordinary nia-nner of tie-plates Vbetween a rail and tie-provides a two-way anti-Creeper which-Connects the railbase to the'plate@ to transmit to theplate and its tie thev lo'ngitudinaly inoveinentsor thrusts ot the rai-15in both directions eaused byl the wave movement ot the rail under traiiie Orb'ytheexpansion and contraction of the rail, while peinittingup and down niovenient or pla'y of the-rail` on thefplate.

vIn the accoinpan'ying drawings, Figi-.1 is atop plan view of'a tieiplate cons-trueted'in accordance with .iny'inventionyFig 2 is a sectional View ot the plate on the lineQ-Q in Fig. 1 with the lower' portion-oa rail in cross-section and a clip" in side elevation; Fig. S'is a fragmentary view'part-ly ,in top plan andfp'artly'in section takenion theline 3 3 in Fig. 2 lookingI in the direction of the arrows; Fig. is a.' detail view siniilar to Fig. 3 but showing theclipinfits initial positionto be seated intheyplate; Fig.-5:is a view similar to FigzQ'f with al tie inside elevationand the? cli p provided with'I aV Vdependingwing; Fig. 6 is a'fragrnentary'view similar to Fig. 3 andtaken/onthe line 6 6 in Fig. 5 looking! in the direction of the? ar'- rows; and Fig. 7 isa: detail 'rear View ofthe ol'ip'shown in Figs: 5 and 6.

In the drawingsthe reference letter A des'- igiiates lthe'base of a rail, B its web broken away to oinit its headforisiniplicity ot illustration, and D is 'one-ot the cross-tiesto which' the plate is spikedin any `suitz'rb'le ina-nner. Y i

'lheytie-platev consists ofY 4a Hat i'netal'lie bo'dyl which `is provided nearioneV edge with av rail-abutting shonlder '2y and'1 with' Aspike-l hol'es f8 to rece-ive the .spikes which-engage theunderlying tie to hold the plate onA the -tie vand-the' rail on .the plate.v The railzis connected to- .the plate by: an anehor clip which grips they rail-base and is kseated ina seat in the plate provided with a resi'l'ient gate which allows the clip to. be passed throughit'v to enter its seat and elainpthe rail rand -then Closes to retain 'the clip in Apla-ce on the rail and in its seat. The plateis provided in one orbothof vits eiidslwith a longitudinal slit 4C which extends fronti-near its center through one end of the plate and divides that end of thexplate into sections which; canbe teinporarilyspread apart to pass the clip into its seat and then closedI to lo'clr the clip imposition. The slit is prefer,- a'b'ly near one side of the plate and is laterally enlarged-near its outer end where the edge `of the'fraiLbase overlies it to torrn areota'ngul'ar Seat 5, and the outer ends of its walls ,are laterally beveled or flared to or'ln cal central line to provide a wedge-shaped toe 10. y.

In the form shown in Figs. 5, 6 and? the tie-plateis of sufficient size to provide a suitable sea-ting' surface' tor the rail-base yand to haveone of'its sides extend-beyond the side of the tiel D,` aszshown for example in Figs. 5 and 6, when the plate is spikedv thereto in track. The extended or o'v'erhanging side of the tie-plate is provided near its edge with a'slit .tand a seat/5y of thesaine construction as above described; and'tneclip is provided Awitha depending wingll on its lower aw togabut against'the side` ot the tie to transmit longitudinal'thrusts'oifthe rail in one-.direction directly yagainst the tie.

`The dimensions of the parts are suchthat whena plateis assenibled under railsbase the edges of the' `latter overlie the clip-seats with one edge' bearing againstthe shoulder 2i as shown-inFigs. 2f andv 5, and the parts thus. assembled-are spiked to the tie.' A clip is lthen positioned with itsr toe ina belllnouth 6, and lits lower jaw.v 9 is driven through the gate 12 formed by theouter 100 portion of the slitA 4in theinargin of the plate until? itenters the associated seat 5; the passage of the clip through the gate causes the sections-vof the plate to spread apart as shown in Fig. 4. and after the clip 105 enters its seat the gate isolosed andthe outer 'walls' of' the seat retain the elip: in placev on the edge ofthe rail-'base-as shown-in Figs. 2^ and 5.V As the Clip is narrow, being only about'tlve-eighth'sA oit an inch wide 110 in practice, it avoids distortion of the metal of the plate When the parts are being assembled; and as the height of the lower j aw may be proportioned to the thickness of the associated plate without necessitating any adzing of the ties7 the clips will not rise out of their seats under the vertical action of the rails due to their Wave-like motion from passing traflic. As the seat in the tie-plate is spread apart laterally when the anchorclip is moved into position therein the dimensions of the seat and clip can be such that when the parts are assembled the sides of the seat will lit snugly against the side Walls of the clip to enable the clip to abut against the tie-plate in either direction of the rail Without lost motion or play; this effective engagement of the anchoring parts results from the mode of their assemblage which is made possible by the slit plate. The anchor-clip grips the rail and bears against the sides of the seat in the tie-plate, so that all longitudinal movements or thrusts Which the rail may have in either direction are taken by the tie-plate, and as the tie plate is spilred to the tie the resistance of the latter embedded in the ballast is utilized 'against the longitudinal movements of the rails in both directions. By this organization a rail-anchorage is provided which resists rail-creeping in both directions While permitting vertical movement of the rails on the plates.

While I prefer to provide each plate Awith two seats as shown, it is obvious that only a single seat may be used or desired, in which case it Will preferably be located at the shoulder-end of the plate as shown for example in Figs. 2 and 5. The seat may be of any convenient size and form, and the clip may be of any suitable construction to cooperate With the seat and act as a stay or anti- Creeper for the rail. 'Iie plates have been made by various methods for many years of malleable iron, wrought iron and steel of various grades affording sufficient elasticity to permit them to be used in the manner and for the purposes above described; With some steels the sections Will automatically close the gate behind the clip, but when other materials are used it may be necessary to do this by driving the sections together. In either case my invention. may be realized with Well-known commercial plates.

I claim:
